+* Optional arguments in user-defined functions
+
+User-defined functions can take optional arguments. In declaration,
+optional arguments are separated from the mandatory ones by a
+semicolon. For example:
+
+ func foo(number a, number b; string c)
+
+This function is declared with two mandatory arguments (a and b), and
+an optional one (c). Subsequently it can be invoked either as
+
+ foo(x, y, z)
+
+or
+
+ foo(x, y)
+
+When invoking such functions, any missing arguments are replaced with
+default values:
+
+ - 0 for numeric arguments
+ - "" for string arguments
+
+Thus, continuing our previous example, the invocation `foo(x, y)' is
+equivalent to `foo(x, y, "")'.
+
+* New statement #include_once
+
+This statement works exactly like `#include' except that it keeps
+track of the included files. If the requested file has already been
+included, `#include_once' returns silently, while `#include' issues
+an error message.

+* DNS functions
+
+DNS functions are reemplemented in two layers:
+
+1. Primitive calls:
+
+- string primitive_hostname (string IP)
+- string primitive_resolve (string S [, string DOMAIN])
+- number primitive_hasmx (string DOMAIN)
+- number primitive_ismx (string DOMAIN, string IP)
+
+These functions throw an exception if the requested lookup operation
+fails.
+
+2. Traditional calls:
+
+- string hostname (string IP)
+- string resolve (string S [, string DOMAIN])
+- number hasmx (string DOMAIN)
+- number ismx (string DOMAIN, string IP)
+
+These are implemented in MFL and work exactly as their predecessors in
+3.1.x branch.
+
+To use the traditional calls, include file "dns.mf".
+
+* Function `match_cidr'
+
+This function has been reemplemented in MFL. To use it, include
+"match_cidr.mf".
+
* New statement `throw'
The `throw' statement throws the given exception. For example:
